Brenton Fitzgerald

Owner and Head Instructor Fluid Jiu Jitsu, Ironman

Brenton has been practicing Brazilian Jiu Jitsu since 2002. Before that he was an accomplished wrestler starting at the young age of 9, in 1986. He started under Professor Henry Matamoros and earned the rank of brown belt under Professor Matamoros.

After over 5 years at the rank of brown belt, on May 17th 2015, Professor Matamoros instructor Master Pedro Sauer promoted Brenton to Black Belt. Master Sauer received his Black Belt from Grand Master Helio Gracie who is considered to be the founder of Brazilian Jiu Jitsu.

That means Brenton is 2 degrees of separation from the foundation of the art. He has trained with Professor Jon Freidland (also a Master Sauer Black Belt) at Neutral Ground for the past years and is excited to carry on the tradition of great Jiu Jitsu under the banner of Fluid Jiu Jitsu.

My Story

I was a very good wrestler. At age 24 and my career behind me, I challenged anyone and everyone to wrestling matches. My sister was dating a man named Mike Contreras. He accepted my offer. I took him down, I held him on his back for 3-4 minutes. This was well more than enough to win a wrestling match, it did not win the fight. I could not make him quit. After a few minutes I got tired and Mike effortlessly lifted me off of him (he was 20lbs lighter than me) and turned me 90 degrees in mid air, set me down very gently and applied an arm bar. I had to tap out and give up so he would not break my arm. I asked how he did that and he said Brazilian Jiu Jitsu! I had been a wrestler for 15 years, Mike had been in Jiu Jitsu for 2 years and never wrestled before.

I found Professor Henry Matamoros 2 weeks later and have not stopped training since. I never wanted to be beaten that bad ever again. I have been beaten since. That is part of being humbled by this art, but I also want to show the average person how to beat a good wrestler with great technique just like I was beaten.

Peter Kulibert

Kickboxing Instructor

Peter has been training in Taekwondo and Karate since 2007 and holds a black belt in both. He has also trained in Muay Thai since 2013. Peter has been teaching striking techniques and strategies for about 8 years. He also has competition experience in kickboxing, and was the Milwaukee Rumble 2016 champion.

I started training in Karate and Taekwondo my freshman year of college. I had been attacked and bullied a few times throughout my childhood so I wanted to know how to protect myself. The martial arts club at my school wasn’t for profit, so the training was the number one priority. Our motto was “indomitable spirit” and our testing reflected that. To earn my black belt, I had to survive a thirteen-hour test that was designed to break my body down and show how much heart I have. I have aspirations of fighting mma professionally, but my bigger passion is coaching. Since “iron sharpens iron” I intend to improve myself as I improve my training partners.
